Our material can not be listed as much as, or more portions for reference, there can be no doubt hotline: 0769-33367273, QQ: 1342110109 13669874955 DT4E Li Ling iron iron is very soft metal, silver-white metallic luster, neither made swords and guns, nor cast iron pot, plowshare. But pure iron after a certain amount of carbon, it becomes steel that we use in all aspects of the. Carbonaceous iron becomes more than 0.02 percent lower hardness can pull wire, rolling thin white iron and other low-carbon steel used. Steel in the range of 0.25 to 0.6% of the iron in the carbon content is called carbon steel, medium hardness, can be rolled into construction steel, steel, nails and other products. Iron carbon content from 0.6 to 2.0 percent when it became a high hardness can be prepared sword and die like a high-carbon steel. Low, medium and high carbon steels together called "carbon steel." If the iron content of more than 2.0% of carbon becomes hard and brittle cast iron pot can, radiators, pig iron a plow. Usually pig iron carbon content of 3.5% -5.5%. So the difference between pure iron, steel and cast iron main different is that the carbon content. Pure iron is a steel, its chemical composition is mainly iron content in 99.50% -99.90%, the carbon content of 0.04% or less, the other elements, the less the better. Because it is actually not a real pure iron, so called it A near-iron steel industrial iron. General industrial iron special soft texture, toughness particularly large, good electromagnetic properties. There are two common specifications, one is as deep drawing material may be stamped into a very complex shapes; the other is a magnetic material having a low sense of diamagnetic high magnetic widely used in electrical, electrical components, magnetic materials, amorphous articles, relays, sensors, automotive brakes, textile machinery, electric meter solenoid valve, etc. products. Higher than the melting point of iron in moist air difficult to rust than iron, in the cold concentrated sulfuric acid can be passivated. DT4E profile: iron alloy carbon content is less than 0.02%, also known as wrought iron (0.02-1.7% carbon content called steel, carbon content of 1.7-4.3% called pig). Wrought iron by the direct reduction of iron ore with carbon, or the product of the molten pig iron and impurities through oxidation obtained; lower former smelting temperatures, using earlier, although the latter temperature is higher, but the melting point of iron due to increased carbon and thickens; both are difficult to completely separate the slag and iron, wrought iron so often contain a small amount of residue, display of fibrous tissue in the process.
